Brunch—like twilight, sporks, skorts, friends with benefits, and so many other things that make life worth living—is not quite one thing and not quite another. Celebrate everyone's favorite mutant mealtime with today’s Groupon: for $5, you get $10 worth of Sunday brunch at Baker Street Rue.

Baker Street Rue’s expert cuisine wizards employ fresh ingredients to craft delectable dishes that populate an energy-packed Sunday brunch menu served from 8 a.m. to 3 p.m. Assail the senses with a selection of protein-filled egg dishes whipped up with vegetables, meat, and local farm-fresh eggs, such as a spinach and feta cheese egg sandwich ($4) tucked between a bagel, sweet bread muffin, or edible bookends. From a list of add-ins, diners can transmogrify red peppers, baby spinach, or goat cheese into a purposeful scramble or bustling omelet ($6 for one add-in). Lunch leaners can indulge in afternoon-styled sandwiches such as a Frankenstein panini ($8), which jolts chicken, bacon, and science into a single edible concoction, or the roasted pork shoulder sandwich smothered with chipotle barbecue sauce ($8).
